Abstract

FIELD OF THE INVENTION The invention relates to foundry, in particular, to the manufacture and installation of rods and the tilting of half-molds. The purpose of the invention is to improve the accuracy and reduce energy consumption. An automatic machine for making rods and putting them into sand form includes a four-position vertical carousel for turning and setting rods 10. Each position of the carousel contains a fixed part 3 of the core box, a movable part 4 with a long stroke cylinder of pairing with a half-form and a double roller table section, 8 half-molds . The rods are installed from part 4 of the core box by mating with the half-form, with further tilting in the assembled state and removing a part of the core-box, leaving the rods in the half-mold 9. The machine allows 4 sets of rods to be attached to the carousel. The operations at different positions of the carousel are carried out simultaneously, which improves the performance of the rods. 1 il. i (G With her her about:

Description

The invention relates to foundry, in particular, to the manufacture and insertion of rods and the tilting of half-molds and can be used in an automatic line.

The purpose of the invention is to improve the accuracy and reduce energy consumption.

The drawing shows a schematic diagram of an automaton for making rods and putting them into a sand mold.

The machine includes a body 1 of a carousel with a rotation drive and windows 2 for receiving and discharging half-molds, fixed parts 3 rod bars, movable parts 4 bar boxes with long-stroke cylinders 5, guides 6, sandblasting head 7, double roller sections 8 and the installation of half-form, half-form 9 and rods 10.

 The machine works as follows.

At position a, the sandbag head 7 descends and fills the core box with the mixture, the carousel turns. In position b, the cylinder opens the core box, lowering the movable part 4 of the core box with a set of rods 10. In the gap between the parts of the core box through the window 2 on the roller table section 8 enters the mold 9, located a plane of the connector down, then the cylinder 5 lifts part 4 of the core box the mold 9 and the rods 10 enter the sign portions of the mold half, then the carousel rotates, with the core box assembled with the mold half moving through position c to the position

In position e, cylinder 5 lifts part 4 of the core box, leaving the rods in the mold half and the half mold with a set of rods protrudes from the carousel through window 2 already with the plane of the connector up, then the carousel rotates, moving this core box to its original position, where the box is assembled and the installation cycle is repeated. At the same time, the operations of assembling the box and filling with the mixture at position a, entering the half-form and lifting part of the core at position b, lifting part of the core box leaving the rods and dispensing the half-form at position e occur simultaneously.

Thus, in the automaton, the problem of inserting the rods into the half-form is solved, as a result of which accuracy is achieved and energy consumption is reduced.
